Bolted to thc exterior of the cylinder 5 is avertically-arranged rack 12,Y that is arranged direetly opposite therack formed on the rib 9, and both of said racks occupy positions withinthe `frame 3 in front of t'he ring 4. Meshing'with these racks is apinion 13,

that is c arried on the forward end of a sleeve 14, that is iournale'din a portion of the frame 3, and said sleeve is provided with asquareaperture 15, in which is arranged to slide a short shaft 16. The rearend of this shaft 16 is connected by a universal joint 17fto-the forwardend of a shaft 18," that is arranged in suitable-bearings formed in theends gof the arm 2. This universal joint is in direct alinement u iththe hinge between the'arm 2 and the frame 3. A sliding clutch 19 ismounted on the outer end ofthe shaft 18, which clutch rotates with saidshaft, and a suitable lever 20 is connected to said clutch for throw ingit. into engagement with clutch-faces formed on pinions 21 and 22, thatare arranged for rotation on the shaft 18 and driven indifferentdirections. This lastJ mentioned lmechanism is for the purposeof reversing the rotation of the shaft 18. Mounted for rotation luponthe post 1 a sho'rt distance below the arm 2' is a horizontally-arrangedgear-wheel 23, that is suit ably driven and which is provided in its topface with a cam-groove 24.

25 indi' ates an arm that projets `downpivoted an arm 26, that tar-riesa roller 27 on its rear end, whit h roller rides in the cantgroove 24. U

'lhe mechanism just desg-rihed provides vcarried tleltelv vertifally andoutwardly from the end of the arm 2. Y' y l l Arrange-d for vertit almovement within the iylinder 8 isa small cylinder 28, thatis tension 29,that 'prt-jects some distaneeabove thehupper end of t he t vlinder 8.Formed integral with the lower end of this cylinder 28 is adown'wemily-projecting tubular stemBO, that proie-sts through the lowerend ofthe ,laf ent its lower end with a flange 31. Formed an unwarllv-nr .zlet-ting bracket 32, the exwat-diy from the frame 3 and towhichis means for swinging the frame 3 and parts IOC provided at itsupper end with a tubular ext outer ylinder 5 and whif. h is provided1ad-- Irc integral with the front side ol the rmg 4 is f lar extension29 and through the cylinder 28, the lower end of said rod being providedwith a lpistonihead 65,y that operates throughout the inner cylinder 28.

The upper end of the extension29 has aILexhaust-port 40, and a similar port 41 is formed in the upperend of the cylinder8. The extension 29 is also formed with an externalgroove 38 to receive a key 37, which also engages a keyway in a beveledgear-pinion 42, that is supported by the arm 36, that projects from thebracket The pinion 42, which rotates the tubular extension 29 andcylinder 28, mesheswith a pinion 43, that is fixed upon the end' of ahorizontally arranged shaft 44, rotatably mounted in the bearing 35.Fixedly mount ed on the shaft 44 on the oppositeside ofthe bearing 35from the pinion 43 is a drive-gear 45, and the end of the shaft 44adjacent this gear 45 is connected by a universal joint 46 to a link 47.

Formedintegral with and extending upwardly from the rear end of the arm2 is va bracket 48, and4 mounted' for rotation in the upper .end thereofis the lower end of anjin'- clined tubular shaft 49. Arranged toslide inthis shaft and to rotate therewith is a shaft 50, the upper end of whichis connected' byv a universal joint 51 to the rear end of the link 47.Mounted on the lowerend of the tubular shaft 49 is a beveled pinion 52,which meshes with a like pinion 53, carried by one end Aof a shaft 54,that is journaled in the bracket 48. Located upon the opposite end ofthis shaft is a belt-wheel 55, that' is continuously driven.v'lhemechanism just described rovides means for continuously rotatingtllile inner cylinder 28, that carries the `stem, 30. .The brackets 32and 34 are extended slightly tor one side of the .vertical plane4occupied by the tubular extension 29, and formed invsaid brackets justbelow the arm' 36 are the alined bearings 56 and 57. Arranged forrotation in thesebearings is a\ horizontally-arranged shaft 58, on therear end of which is fixed a lpinion 59, that' is in mesh with anddriven by the pinion 45. Located on the forward end of'this shaft 58 infront of the bracket 32 is a disk 60. Pivotally connected to a pointadjacent the edge of this disk is the lower end of a connecting-rod 61which extends upwardly, and passing'through the upper end of said rod isa pin or bolt 62, that passes through the slot 33 and is seated in ablock 63. -This block is rigidly connected to the upper end of a rod 64,that extends downwardly through the tubu- .ter of theopeningv 68.

the ring 4 is a plurality-of rods 66, which are secured to the top of arectangular block 67, that is arranged a short distance below the lowerend of the inner cylinder 28.

gated opening v68, and extending upwardly from the top of said block isan annular flange 69. Arranged for rotation upon the block around thisflange 69 is a ring 70, from which projects outwardly anoperating-handle 71.

`Fixed to opposite sides of the block 67 is a pair ofupwardly-projecting lates 72, the upper ends of which are provi ed withintegral inwardly-projecting flanges 73. Arranged to slide on top of thering 70 and between the flanges 73 is a pair of plates 74, the innermeeting edges of which are provided with semicircular cut-away portions75, that form a circular opening immediately over the cen- Formed in,each one of these plates 74 isan inclined slot 76, into which projectpins 77, that are seated in the ring 70. These slots 76 are arranged atthe same angle and are so disposed as that when the ring 70 is slightlyshifted the pins 77, riding in'said slots, will cause the plates 74 tospread a art. Fixed to the tops of theplates 74 are the mating halves 78of a neck-ring, that rojects downwardly through the elongatedp opening68, and which neck-ring is so formed on its inner face as to shape andcontour to the the neck of the bottle that improved machine.

give the proper upper portion of is formed by my The steml 30 projectsdownwardly into this neck-ring, and the flange 31 rests' upon acorrespondinglyformedl annular recess 79, that is formed in the top'ofthe mating parts forming said ring.

Hinged to opposite sides of the underside of the block 67 are the matinghalves of a blankmold 80, and formed integral with the outer faces ofthe halves of this blank-mold are the arms 81. Projecting outwardly fromopposite sides of the lower end of the cylinder 5 is apair of arms 82,and connecting the outer ends of these arms withthe outer endsof thearms 81 are the rods 83. .The inner meeting surfaces of the matinghalves of the blankmold are formed with elongated recesses 84, thattogether form a circular recess in which the blank is formed that islater blown into the form of a bottle by my improved machine. The lowerends of these recesses 84 extend to the lower ends of the halves of theblank-mold, so as to form a small opening 85 at said lower end. Hingedto the opposite sides of the lower end of the block 67 are the matinghalves 86, that form the blowmold, and recesses87 are formed on theinner faces of these mating halves 86, in which the bottle is blown. Theupper ends of the halves of the blow-mold and of the halves of theblank-mold are formed to fit the under side of the block 67 and also`tofit against the lower end of the mating halves of the neckl Formedlthrough the center of this block 67 is an elon` lIO ' post 1 that bearsagainst the under side of said arm .ofvertically-arranged!fconnecting-rods 92.

connected to the outer ends of short arms 93,

'the blank-mold will dip into the l:molten glass part continuous rotarymotion Ato the shaft ring. llinged to the lower portion of thel is aforwardly-projecting arm 8,6, that is provided at. its outer' end with ablock 87, in the top of which is formed a recess 88, that is constructedto iit the lower ends ol the halves 86 of the blow-mold. A shaft 89 istransversely arranged Vfor rotation beneath the arm 86, andvsaidshaftarries a cam 90,

86. As the shaft 89 is rotated the cam moves the arm 86 upwardly andbrings the bloek 87a upwardly against the lower ends of the matinghalves of the blow-mold. Formed integral with and extending outwardlyrfrom the` outer faces of the blow-molds lare the arms 9'1, to which aresecured the lower ends The upper endsof these rods 92 are pivotally`that are xed to and project outwardly from the upper end of thecylinder 8, and which arms-93 are arranged at right angles to the arms82.

My im roved machine, .constructed as described, 1s' located adjacent aglass-furnace and is arranged so that when theframe 3, ring 4, and partscarried thereby are swung vertically the lower ends of the halves 80 ofwithin the glass-furnace; The rotation of the gear-wheel 23, having thecam-groove 24 therein, moves the arm 26 outwardly, and consequentlyswings the frame 3 upon 'its hinge, and thus shifts the entire mechanismcarried byfsaid frame out of a vertical plane, and when the lower endsof the halves of the blank-mold dip into the molten glass the piston 65starts to move upwardly, it being carried/by the piston-rod 64, block63, which are elevated by the vertical movement of the connecting-rod61, moved by the rotation of. the disk 60, which is driven by themeshing of the pinion 45 with the pinion 59. The shaft 54 rotatesconstantly, and the pinions 53 'and 52 and intermediate connections im-44, on which is mounted the bevel-pinion 43, and this latter pinion 1nturn imparts a con;

gethel` with the tubular extension 29 and the inner cylinder 28. Theelevating of the piston -65`within the cylinder 28 creates a partialvacuum Within the opening in ,the blank-mold, and as a result saidopening will be filled with molten glass,y andV during lthe time thismoltenglass is in said blank-mold the stem 20 will be rotating in theupper end of the neck-ring. When the piston 65 strikes the upper end ofthe inner cylinder 28, it will move \said cylinder and the. stem 30upwardly of the cylinder 8, and thls upward movement of said cylinder 28will withdraw the lower end of the. stem from 'the neck-ring, and as awardly and sition.

until it strikes against the upper end result` air will enter throughthe hollow stem and fill the lower portion of the cylinder 28.

The rotation of the (fear-wheel 23 now re-` turr-s the l'rgime 3 to itshorizontal position, and corsetniently the various parts carried in thering 4 are returned to their vertical positions. The sliding clutch 19is now moved by .the lever 20, so that the proper rotary motion isimparted lto the shaft 18 to cause the pinion 13 to so rotate as that.the cylinder 5 and rack 1l carried thereby are elevated, while thecylinder 8 and rack carried therebyr are moved downwardly. 'lnismovement through the connectie-3s 8l 82, aad 83'swingthe mating halves8() of the blank-mold npring/and at the same time the downward movementof the cylinder 8 thrmigli. the connections 91 ,92, and93 move themating halves of the blow-mold downwardly together be.- neaththe bleek67 around the glass-blank. The'mating halves of the blank-mold and ofthe blow-mold are so arranged and hinged as that they openandcltsealternately, and said mating halves swing as indicated by the dottedlines a;=d arrows in Figs. -1 and 2. As soon as the blew-mold closesar.,und the glassblank the piston starts downwardly on its returnmovement, being actuated by the rotation of the disk and the parts movedthereby, and the air that was previously drawn into the cylinder 28 willnow be forced out through the hollow stem and will blow the bottle inthe blow-mold. Previous to this blowing operation or as soon as thehalves of the blow-mold come together the cam 90 elevatesthe arm 86 andbrings the block 87a upwardly against the under side of the blow-mold,(see Fig. 7,) and thus when the bottle is blown it rests upon the centerof this block 87a. The sliding clutch 19 is now reversed, andconsequently a reverse rotary motion is 'imparte-d to the shaft 18, andasa result the cylinder 8 is moved upwardly and at the same time thecylinder 5 moves downi-l wardly. Before this operation-takes place theoperator engages the plates '74,.and consequently separating the .matinghalves 7 8 of the neck-ring, so that the bottle is detached from saidrock-ring, and it 4'may now be removed from the 'block 87a before themating `halves of the blank-mold again s'wiig downwardly into-aclosed-po- The various parts are now ready for another operation,mechanisms operate continuously the movements, as hereinbeforedescribed, take place in regular sequence.

lThe discharge-apertures 40 and 41 allow discharge of the air thetubular extension 29 andthe cylinderv 5v `when the piston and the innercylinder 28' move upwardly. The universal -vjoints 46 and 51 and theshaft 50, operating in a slidoutwardly away from the glass-l /blank,wlucn is held supported by the neckand as the various drivtingfrom theupper ends of.

Thesemolds are alternately opened and closed by the vertical movements of thecylinders 5 and 8, which are actuated by the engagement of the pinion 13with the racks11and12.` A
